Abstract (en)
[origin: WO2022129077A1] A positive electrode active material for batteries which comprises Li, M', and oxygen, wherein M' comprises: Ni in a content a between 60.0 mol% and 75.0 mol%; Co in a content x between 0.0 mol% and 20.0 mol%; Mn in a content y between 0.0 mol% and 35.0 mol%, a dopant D in a content z between 0.0 mol% and 2.0 mol%, Al, B and W in a total content c between 0.1 mol% and 5.0 mol%, wherein the active material has an Al content AlA, a B content BA, and a W content WA, wherein a, x, y, z, c, AlA, BA and WA are measured by ICP, wherein AlA, BA and WA, wherein the positive electrode active material, when measured by XPS analysis, shows an average Al fraction AlB, an average B fraction BB and an average W fraction WB, wherein AlB/AlA, BB/BA, and WB/WA are all larger than 1.0, and wherein the positive electrode active material is a single crystalline powder.
